[stunnel-users] stunnel 4.35 hangs on slackware64 13.37

If I rotate stunnel logs with logrotate and have logrotate send SIGUSR1 signal to stunnel, stunnel doesn't close and reopen a new log and hangs. If I rotate stunnel logs and have logrotate send SIGHUP to stunnel, stunnel writes two lines to a new log but hangs after then. It could be a CPU problem because my D525 ATOM CPU had a problematic history with other programs. But I'm not sure of this. Can anybody else reproduce the problem?
